You want to leave the motorway at the next exit. What is the correct course of action in this situation?

Your answer is correct because when you want to leave the motorway at the next exit, the first step is to observe the traffic behind you. This helps you understand the situation and ensure that lane changes or slowing down will not surprise or endanger other drivers. The second correct action is to turn on your right-side indicator in advance to signal your intention clearly to other road users.

Braking suddenly or reducing speed too early can be dangerous on a motorway where traffic moves fast. The proper rule is to maintain your speed until you have moved safely into the exit lane, where you can then slow down smoothly. Starting to brake early on the main lanes can confuse or disrupt the flow of traffic behind you.

So, observing the traffic and indicating early are essential steps for safe and predictable lane changes when exiting a motorway in Germany.
